The present invention relates to computer storage system. More specifically, the present invention relates to hard-disk drive for memory storage.

BACKGROUND

Data storage is essential to digital processing systems including computers, smart phones, and/or network devices. With increasing demand of instant information over wired or wireless communication network, large capacity storage devices capable of storing voluminous files and applications are in demand. One type of storage device such as hard-disk drive (“HDD”) are conventionally employed to store digital information such as data, video, audio, and/or control information for computing devices. For example, a digital processing system such as a computer may house an HDD for storage. Also, conventional network attached storage (“NAS”) system, which is another type of network storage device, may use one or more HDDs for data storage.

An HDD, also known as hard file and/or disk drive, contains one or more rotating discs coated with magnetic medium capable of storing digital information. A typical HDD can store relatively large amount of data. To increase storage capacity, a conventional approach is to employ multiple HDDs wherein each HDD is engaged and enclosed in an HDD tray. Multiple HDD trays can be installed in a storage bay, tower, or unit.

A problem associated with a typical HDD or HDDs in a data storage system is that it is cumbersome to maintain, access, transport, and/or replace one or more HDDs partially due to the tools and/or special equipments required. For example, to access or reach a HDD(s), a set of tools is typically required to remove and/or install HDD(s) in a network storage system. Replacement or addition of HDD often involves a laborious installation procedure including opening system's physical enclosure to reach or access the HDD(s).

SUMMARY

Embodiments of the present invention disclose an HDD assembly or device able to secure an HDD to an HDD tray using semi-flexible strips without using special tools. The HDD device, subsequently, is attached or plugged into a computing system, router, network device, and/or a storage bay. The HDD assembly or device, in one aspect, includes a tray, a U-shaped semi-flexible anchoring (“USA”) frame, and an HDD. The tray has a base, a front panel, a right side panel, and a left side panel. The right side panel and the left side panel include tracks along longitudinal edges of the right and left side panels. The USA frame includes a front piece, a right strip, and a left strip, wherein the right strip is configured to be fitted in the track of right side panel.

FIG. 1 is a diagram 100 illustrating a top view of an HDD device using anchoring strips in accordance with one embodiment of the invention. The HDD device, herein, can also be referred to as HDD assembly, HDD carrier, HDD assembly device, and the like. Diagram 100 includes a front cover 102, a tray, a U-shaped semi-flexible anchoring (“USA”) frame, and an HDD 106. Front cover 102, in one example, situated in the front of HDD device is used as a user interface panel allowing a user to access the HDD device. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or units) were added to or removed from diagram 100.

The tray, also known as a HDD tray, is formed with a base and three sides along the edges of the base. Three sides, viewing from the front, include a front panel 108, a right panel 110, and a left panel 112 wherein one end of front panel 108 couples to right panel 110 and another end of front panel 108 couples to left panel 112. Front panel 108 coupling to front cover 102 facilitates a locking mechanism between the tray and the USA frame. In one aspect, the locking mechanism allows a user to release the USA frame from an engaged configuration to a pullout configuration via front cover 104. Front panel 108, in one example, is coupled with front cover 102 wherein cover 102 provides a function allowing a user to retrieve the HDD device from a tower or a rack, as well as allowing a user to release the USA frame from the tray.

Right panel 110, in one embodiment, is structured in a rectangular wall which has a top side, a bottom side, two ends, wherein the bottom side of right panel 110 is connected to the edge of the base. The length of right panel 110 should have similar dimension as HDD. On the top side of right panel 110, which is at the opposite side of the base, contains a track. The track, in one embodiment, allows anchoring strip(s) to conditionally slide along the right panel 110. The sliding motion, for example, can be either moving away from front cover 102 or moving toward to front cover 102.

Left panel 112, in one embodiment, is also structured in a rectangular wall having a top side, a bottom side, two ends, wherein the bottom side of left panel 112 is connected to the edge of the base. Left panel 112 is situated opposite from right panel 110 across the base and is erected from another edge of the base to form another side of the tray. The length of left panel 112 should have similar dimension as HDD. On the top side of left panel 112, which is at the opposite side of the base, contains a track. The track, in one embodiment, allows anchoring strip(s) to conditionally slide along the left panel 112. The sliding motion, for example, can be either moving away from front cover 102 or moving toward to front cover 102.

It should be noted that front panel 108, right panel 110, left panel 112, and base can be fabricated in a single tray construction. The tray, in one aspect, can be made of various materials, such as, but not limited to, metal, aluminum, alloy, plastic, polymer, ceramic, composite, and the like. The height of tray, in one example, has a range from 5 millimeter (“mm”) to 20 mm. While an exemplary length of the tray 140 can have a range between 80 mm and 200 mm, the width of the tray 142 has a range from 50 mm to 100 mm. A function of the tray is to house HDD 106 wherein the tray can be further plugged into a tower or rack.

The USA frame, in one embodiment, includes a front piece 114, a right strip 116, and a left strip 118. It should be noted that strip is also known as anchoring strip, semi-flexible anchoring strip, fastener strip, and the like. Front piece 114 includes a locking mechanism 104 and is used to interface between front panel 108 and the front side of HDD 106. Locking mechanism 104 locks the USA frame to the tray and/or release the USA frame from the tray. Front piece 114, in one example, has similar dimensions as front panel 108.

Right strip 116 further includes a stopper 120 and multiple engaging pins. One end of right strip 116 is coupled to front piece 114 and it has similar dimensions as right panel 110. At least a portion of right strip 116 can be inserted inside of track of right panel 110 whereby right strip 116 can slid along right panel 110. Right strip 116 provides an interface function between the tray and HDD 106, which secures, fastens, and/or attaches HDD 106 to the tray. Right strip 116, in one aspect, is made of flexible materials, such as plastic, fibers, polymer, aluminum, alloy, metal, and the like.

Similarly, left strip 118 includes a stopper 122 and multiple engaging pins. One end of left strip 118 is coupled to front piece 114 and it has similar dimensions as right panel 112. At least a portion of left strip 118 can be inserted inside of track of right panel 112 whereby left strip 118 can slid along right panel 112. Left strip 118 provides an interface function between the tray and HDD 106, which secures, fastens, and/or attaches HDD 106 to the tray. Left strip 118, in one aspect, is made of flexible materials, such as plastic, fibers, polymer, aluminum, alloy, metal, and the like. Front piece 114, right strip 116, and left strip 118 can be fabricated together into one single structure.

HDD 106 is a hard file and/or disk drive capable of containing one or more rotating discs coated with magnetic medium. HDD 106 is able to store digital information on each disc. HDD 106, in one example, includes four or more mounting holes 130-136 configured to anchor HDD 106 to a frame using fasteners such as screws and pins. It should be noted that solid state memory cards can be used in place of HDD 106. The solid state memory cards include semiconductor memory devices, such as flash memory, Magnetoresistive random-access memory, or the like.

An advantage of using the USA frame is that allows a user to assemble and/or disassemble an HDD without using any tools, which simplifies HDD replacement or installation process. Another advantage of using the USA frame which surrounds three sides of HDD 106 is that the USA frame is able to provide shock absorption.

FIG. 2 is a diagram 200 illustrating a top view of an HDD device with a portion of an HDD sliding out of a tray in accordance with one embodiment of the present invention. Similar to diagram 100 of FIG. 1, diagram 200, which illustrates a pullout configuration, includes a front cover 102, a tray, a USA frame, and an HDD 106. Front cover 102, in one example, situated in the front of HDD device is used as an interface panel which allows a user to access the HDD device. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or units) were added to or removed from diagram 200.

The tray is formed by base 202, front panel 108, right panel 110, and left panel 112. One end of front panel 108 couples to right panel 110 and another end of front panel 108 couples to left panel 112. Front panel 108, in one example, receives or couples to front cover 102 and facilitates a lock function between the tray and the USA frame. The USA frame, in one embodiment, is formed by front piece 114, right strip 116, and left strip 118. A function of front piece 114 is to disengage the USA frame from the tray using locking mechanism 104. Upon disengagement, the USA frame can slide within a predefined distance as indicated by arrow 206.

Diagram 200 illustrates an HDD device in a pullout configuration. The pullout configuration illustrates a condition in which the USA frame is pulled away from front cover 102 until stoppers 120-122 catch stop latches 220-222 on the side frames or panels of the tray. Stop latches 220-222, in one aspect, are situated in right panel 110 and left panel 112, respectively. When stopper 120-122 catch stop latches 220-222, the USA frame, in one embodiment, stops moving away from front cover 102. Depending on the applications, distance 206 can vary. An advantage of restraining the USA frame from being completely pulled out of the tray is that it prevents misplacement of the USA frame associated with the tray. In one aspect, the USA frame matches with the tray.

When the HDD device is in pullout configuration, right strip 116 and left strip 118 can be flexibly tilted away from HDD 106 as shown by arrows 208-210. As right strip 116 bends away from HDD 106 as indicated by arrow 208, engaging pins 230-232 on strip 116 are disengaged from mounting holes 130-132 on HDD 106. Similarly, when left strip 118 bends away from HDD 106 as indicated by arrow 210, engaging pins 234-236 are disengaged from mounting holes 134-136 of HDD 106. When engaging pins 230-236 disengage with mounting holes 130-136, HDD 106 can be dismounted or removed from the USA frame. It should be noted that the flexibility of the strips can vary depending on the applications.

FIG. 3 is a diagram illustrating a top view of an HDD device or assembly showing the USA frame without an HDD in accordance with one embodiment of the invention. Similar to diagram 200 of FIG. 2, diagram 300, which illustrates a pullout configuration, includes a front cover 102, a tray, and a USA frame. While the tray is formed by base 202, front panel 108, right panel 110, and left panel 112, the USA frame, in one aspect, is formed by front piece 114, right strip 116, and left strip 118. The top portions of right panel 110 and left panel 112 include tracks for housing the flexible strips such as strip 116-118 for sliding. End view 306 of left panel 112 as indicated by arrow 302 illustrates a “7-shaped” or “hock-shaped” structure 308 which is used to facilitate movement of strips 116-118. For example, an anchoring strip such as left strip 118 can conditionally slide within the hock-shaped structure 308 while structure 308 limits how far the strip can move.

FIG. 6 is a 3D perspective diagram illustrating a USA frame in accordance with embodiments of the present invention. Diagram 600 includes front piece 114, right strip 116, and left strip 118. Front piece 114 also includes a locking mechanism 104 and a lip 608. While lip 608 may be used to pull the USA frame away from a tray, locking mechanism 104 is used to lock or seat the USA frame to the tray. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or units) were added to or removed from diagram 600.

Right strip 116 includes engaging pins 230-232, elastic clamp 502, and stopper 120, wherein top portion 602 of right strip 116 is used to fit inside of the track on the right panel. While stopper 120 is used to determine how far the USA frame can move within the tray, engaging pins 230-232 and elastic clamp 502 are used to stabilize or fasten HDD to the USA frame. Left strip 118 includes engaging pins, elastic clamp 606, and stopper 122, wherein top portion 604 of right strip 118 is used to fit inside of a track on the left panel. While stopper 122 on left side is used to determine how far the USA frame can move within the tray, engaging pins 230-232 on right side and elastic clamp 502 are used to stabilize or fasten HDD to the USA frame.

FIG. 7 illustrates exemplary diagrams showing a storage bay or carrier stack having multiple HDD devices configured in a stacked configuration in accordance with one embodiment of the present invention. Diagram 700 illustrates an HDD carrier 710 configured to house an HDD device. In one aspect, HDD carrier 710 contains rails 720 for receiving HDD device. For example, rails 720 of HDD carrier 710 are configured to allow a tray or HDD tray of HDD device to slide in and out of HDD carrier 710. HDD carrier 710 further includes a top plate 702, a top stacking anchor 706, and multiple stacking stands 708. While top plate 702 provides protection to HDD 106, top stacking anchor 706 and stacking stands 708 are used for stacking multiple HDD carriers 710 in a horizontal configuration to form a storage bay. In one example, each HDD carrier 710 has four stacking stands 708.

Diagram 750, in one embodiment, includes a storage bay containing four HDD carriers 710 stacked in a vertical configuration. It should be noted that stacking stands 708 are configured to interlock with another HDD carrier 710 situated below whereby a stack of HDD carriers can be safely structured or stacked. In one embodiment, stacking stands 708 are made of shock absorbing material to provide additional shock protection to each HDD carrier 710.

An advantage of having a stacked storage bay is that the capacity of storage can be scaled depending on the applications. Each HDD carrier 710 can be independently removed, added, replaced and/or adjusted without affecting operation of other HDD carriers in storage bay. Storage bay or carrier stack may be used for network storage device for a computer or network management system.

Another advantage of employing storage bay or carrier stack using HDD devices is that maintaining and accessing HDDs are relatively easier since minimal or no tools are required. Furthermore, employing HDD device in a storage bay minimizes requirement for spare parts such as screws and trays.

The exemplary aspect of the present invention includes various processing steps, which will be described below. The steps of the aspect may be embodied in machine or computer executable instructions, or manual procedures. Alternatively, steps and/or procedures may be performed by a user or administrator.

FIG. 8 is a flowchart 800 illustrating a process of removing and/or replacing an HDD from an HDD assembly or device in accordance with one embodiment of the present invention. At block 802, a process of mounting and/or replacing an HDD device includes extending the USA frame away from a HDD tray or a tray to a predefined distance indicated by a stopper which is located on the right strip of the USA frame against a side of tray. In one example, the HDD device which contains HDD, tray, and USA frame is removed from a tower or a storage bay. It should be noted that to pull the USA frame away from the tray, a lock located in the front cover needs to be released. For example, a latch may be pulled or pushed by a user to release the USA frame from the tray via a locking mechanism.

At block 804, upon reaching the pullout configuration, the left strip and the right strip are slightly tilted away from the HDD. Since the strips are made of semi-flexible material, the strips are bendable when portions of the strips slide out of the side panels of the tray.

At block 806, once the right and left strips are bent outward, the engaging pins on the left strip and the right strip are disengaged from the mounting holes of the HDD. It should be noted that the left strip and the right strip are bent away from the side of an HDD. Once the engaging pins are disengaged or pulled out of mounting holes, an HDD, at block 808, can be removed from the USA frame. In one aspect, under the pullout configuration, the USA frame is at least partially supported by the HDD tray.

To replace HDD, a new or second HDD is inserted into the USA frame when the USA frame is still in a pullout configuration. After aligning at least a portion of the engaging pins on the right strip to a portion of mounting holes of the new HDD, the right strip is allowed to flexibly tilt toward to the side of the second HDD permitting at least a portion of engaging pins to move inside mounting holes of second HDD so that the second HDD is attached or secured to the USA frame. Similarly, the left strip is allowed to flexibly tilt toward to the second HDD allowing at least a portion of engaging pins on the left strip to move inside mounting holes of second HDD to reinforce the attachment between the new HDD to the USA frame.

It should be noted that the USA frame may further include elastic clamps that provide pushing force to stabilize the new HDD with the USA frame. After new HDD is attached to the USA frame, the USA frame is pushed toward to the front cover along the tracks of tray to secure the HDD to the tray via a locking mechanism associated with the USA frame. In one aspect, the process involves in pushing a portion of an engaging pin into a mounting hole of HDD wherein the mounting hole may contain threads configured to receive a threaded screw for fastening.
